If you want serious wired monitoring with big drivers and a proper desktop-style connection, choose P PUPGSIS M20; if you need an everyday USB-C earbud set with a mic and inline controls for a phone or laptop, choose BLXSounds Earbuds USB C. These two aren't really rivals — they're built for different jobs, and once you see that, the decision gets easy.
• P PUPGSIS M20, biggest strength: full over-ear monitoring design with 50mm dynamic drivers, a 20Hz–40kHz range, 32 ohm impedance and both 3.5mm and 6.35mm jacks — a genuine studio/DJ setup.
• P PUPGSIS M20, biggest trade-off: it's wired only, weighs 12.8 ounces, and has no microphone or inline volume control — it's a listening and mixing tool, not a phone accessory.
• BLXSounds Earbuds USB C, biggest strength: a USB-C in-ear set with a microphone and remote volume control, sold as a 2-pack, aimed at phones, tablets and laptops that dropped the headphone jack.
• BLXSounds Earbuds USB C, biggest trade-off: small 14.2mm drivers, 16 ohm impedance, passive noise cancellation only — fine for calls and casual listening, not for critical mixing.
• Pick P PUPGSIS M20 if you produce, DJ, or mix at a desk and want one durable over-ear pair with a proper adapter for studio gear.
• Pick BLXSounds Earbuds USB C if you want a pocketable, mic-equipped pair for calls, commuting and USB-C-only devices — and you like having a spare in the box.
The M20 is unapologetically a headphone for people who work with audio at a desk. The headline spec is the pair of 50mm dynamic drivers, paired with a wide 20Hz–40kHz frequency range and 32 ohm impedance. That impedance figure matters: 32 ohm is low enough to be driven by a phone or laptop headphone jack, but the large drivers and over-ear, closed cup design are clearly aimed at monitoring, DJ cueing and studio-style listening rather than a jog around the block.
What it does best is versatility in a wired chain. You get a 3.5mm jack and a 6.35mm jack, and the box includes two AUX cables, a 6.35mm adapter and a protective carry case. That means you can go straight into a laptop, an audio interface, a mixer or a home stereo without hunting for adapters. There's also a low stated audio latency of 0.03 milliseconds — irrelevant for casual music, but a reassuring number if you're tracking or cueing and don't want noticeable lag in your monitoring path. The earcups are over-ear with a circular shape, and the materials list mixes polycarbonate, ABS and leather-style earmuffs, with a black finish. The environmental noise cancellation here is the passive, cup-sealing kind, not active electronics.
Who should buy it? Anyone who wants a single over-ear pair for mixing, DJ practice, podcast monitoring or long desk sessions, and who values the included case because the headphones travel between a studio and a gig. Who should skip it? If you mainly take calls on a phone, want inline volume buttons, or want something that disappears into a pocket, this is the wrong tool. There's no microphone listed and no remote control — the controls are push-button on the earcups. It's also 12.8 ounces, which is noticeable on the head over a long day, and it's wired-only, so no wireless freedom. If those trade-offs sound like dealbreakers, the BLXSounds pair is the more sensible fit. If they don't, the M20 is the more capable audio tool by a wide margin.
The BLXSounds set is the opposite philosophy: small, light, and built around the port your phone actually has. It's a USB-C wired in-ear pair with a 14.2mm dynamic driver and 16 ohm impedance. That low impedance is the giveaway — these are designed to be driven easily by a phone, tablet or laptop, no amp required. The earpiece shape is a bud, the enclosure is ABS, and the finish is black.
The practical strengths are the ones you notice every day. There's a microphone, so calls and voice notes work out of the box. There's a remote with button volume control, so you're not unlocking your phone to change the level. The noise control is passive, which for an in-ear bud means it relies on the seal in your ear rather than electronics — you'll hear less around you once they're seated properly, but don't expect active cancellation. The listing also mentions a remote control, a design aimed at small ears, and no ear pressure, which speaks to comfort over longer sessions.
Compatibility is the other big selling point, and it's broad: iPhone 17/16/15 and their Plus, Pro and Pro Max variants, iPad 10, iPad Air 4th/5th gen, iPad Pro and iPad Mini 6th gen, MacBook 12", MacBook Air and MacBook Pro, Samsung Galaxy S24/S23/S22/S21/S20, Galaxy Z Fold and Z Flip, Google Pixel 9/8/7/6/5, OnePlus, and most devices with USB-C output. In other words, if your device has a USB-C port and no headphone jack, this is the straightforward answer.
Side-by-Side: Which Should You Choose?
• Best for studio, DJ and mixing work → P PUPGSIS M20. 50mm drivers, 20Hz–40kHz range, and both 3.5mm and 6.35mm jacks.
• Best for USB-C phones and laptops → BLXSounds Earbuds USB C. Built for USB-C-only devices, no adapter needed.
• Best for calls and voice chat → BLXSounds Earbuds USB C. It has a microphone and inline volume control; the M20 lists neither.
• Best for long desk sessions with a sealed fit → P PUPGSIS M20. Over-ear cup design with leather-style earmuffs and a protective case for transport.
• Best for portability → BLXSounds Earbuds USB C. In-ear buds versus a 12.8-ounce over-ear pair.
• Best for a spare set / sharing → BLXSounds Earbuds USB C. It ships as a 2-pack; the M20 is a single unit.
• Best for easy driveability → BLXSounds Earbuds USB C. 16 ohm impedance runs off almost anything; the M20's 32 ohm is still phone-friendly but aimed at gear.
• Best for latency-sensitive monitoring → P PUPGSIS M20. Its 0.03 ms stated latency is the spec to look at if you're tracking.
If I were buying for myself and my priority was actual audio work — mixing, DJ cueing, monitoring at a desk — I'd take the P PUPGSIS M20. The 50mm drivers, the wide frequency range, the two cable options and the 6.35mm adapter make it the more serious piece of equipment, and the included case means it survives being carried around. The BLXSounds set is the smarter buy for everything else: calls, commuting, phone listening and USB-C-only gear, with a mic and a spare pair in the box. In my opinion, if you're torn, buy the one that matches your port and your purpose — not the one with the bigger numbers. And since both are affordable wired options, it's worth checking the current price on Amazon before you commit.
FAQ
According to the listing, yes — it covers iPhone 17/16/15 models, iPads, MacBooks, Galaxy S24/S23/S22/S21/S20, Galaxy Z Fold and Z Flip, Pixel 9/8/7/6/5, OnePlus and most USB-C devices. The one requirement is a USB-C port.
The BLXSounds earbuds, clearly. They include a microphone and a remote with volume control. The M20 doesn't list a microphone or inline remote, so it isn't the right pick for call-heavy use.
Both rely on passive isolation rather than active electronics. The M20 uses its over-ear cup seal, while the BLXSounds buds depend on the in-ear fit. In my opinion, the over-ear design will generally block more around you, but fit matters more than spec sheets here.
The BLXSounds Earbuds USB C, since it's sold as a 2-pack. The M20 is a single set, so if you want a backup or a second pair for a partner, the earbuds are the simpler route.
